Enjoy Wave Pools, Lazy Rivers, and Slides Until Evening

About this spot

Operating from June 27 (Saturday) to September 23 (Wednesday/National Holiday) 2026, this is a leading outdoor leisure pool representing the greater Tokyo area. The wave pool with a water surface area of 3,323 m² is a star attraction with constant cheers, while the 250-meter lazy river offers pure joy drifting along on a floating ring. For young children, the shallow Anpanman Pool provides a safe environment. Eight varieties of slides offer screams and smiles from elementary schoolers to adults. New in 2026 is "Bubble Oasis," a warm pool where tired swimmers can warm up and rest—a new way to enjoy the park. Water shows and other events keep things exciting from afternoon through evening.

Season & hours

Tips

Admission prices use a dynamic pricing system that varies daily based on expected crowds (check the price calendar on the official website in advance). During summer vacation weekends, entry may be restricted, so advance online purchase is recommended. Secure a poolside spot immediately after entering. With sales booths and restaurants available, you can purchase lunch inside the park. Night pools also operate mid-July through mid-September, allowing you to plan activities into the evening.

Best time to visit

Entering at noon allows you to secure a spot before the peak crowding and enjoy a full 5 hours of play until evening.
